Translucent anhydrous formulations containing particulate commercially available activated aluminium chlorohydrate (AACH) have a perceptible yellowness. The yellowness of translucent anhydrous compositions containing AACH can be ameliorated or eliminated whilst retaining the improved antiperspirant efficacy of AACH by controlling its water content to the range of 9 to 18%. The appearance of yellow formulations in or on a dispensing package, prior to application to the body, can appear to be neutralised to the human eye by employing a dispenser having a complementary colour in wall contacting the formulation, to promote achromicity. The complementary colour of the wall is dark green for yellow formulations.

Antiperspirant compositions

A particulate antiperspirant active material which has been surface treated with an alkanolamine is described. After surface treatment, the surface treatment agent is in intimate contact with the surface or outer layer of the substrate material, that is, the antiperspirant material may be either deposited on the surface or at least a fraction of the agent may be absorbed within the outer layer of the substrate. The resultant particulate material shows a reduced tendency to separate from a liquid carrier phase containing a polyglycol ether and a suspending agent.
